Pinpoint Test BF: The Memory Feedback Warning Chime Is Inoperative

Normal Operation

The Instrument Cluster (IC) receives the memory feedback chime request from the Driver Seat Module (DSM) over the Medium Speed Controller Area Network (MS-CAN) communication bus. When a successful memory set procedure is carried out, the DSM sends a chime request to the IC to sound the memory feedback chime.

This pinpoint test is intended to diagnose the following:

- IC chime function
- DSM
